i have a little problem.
i'm a new french addict and i don't know any adress in paris where i could find good grids.
all books i bought for the moment are so easy, (even those fakes labeled extreme) that they don't need any fun techniques to be solved. the editors don't seem to be serious ones and they label easy grids as "extreme".
i'll try your nightmares i just printed from here, but i think they'll be too hard for me at the moment.

So my question is : do you know which book i should buy (and where in paris for french readers) ? which editor should i look ?
and do you know any web pdf compilation of challenging grids ?

Hello Mike
Welcome on this forum.
I think we al understand the problems of finding realy good puzzles in a book. I only know that Ruud is someone who makes them.
In my whole puzzle carreer i just bought 2 little books and then only coppied puzzles from the internet most of them maked by Ruud.
So i think the best tip came here above from rep'nA
Did you make any clueless specials yet? Or explosions?
